1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Methylenetetrahydrofolate reductase (MTHFR), involved in DNA methylation and nucleotide synthesis, is thought to be associated with a decreased risk of adult and childhood acute lymphoblastic leukemia (ALL). Accumulating evidence has indicated that two common genetic variants, C677T and A1298C, are associated with cancer risk. We hypothesized that these two variants were associated with childhood ALL susceptibility and influence serum MTHFR levels. We genotyped these two polymorphisms and detected MTHFR levels in a case-control study of 361 cases and 508 controls. Compared with the 677CC and 677CC/CT genotypes, the 677TT genotype was associated with a statistically significantly decreased risk of childhood ALL (odds ratio = 0.53, 95% confidence interval = 0.32-0.88, and odds ratio = 0.55, 95% confidence interval = 0.35-0.88, respectively). In addition, a pronounced reduced risk of ALL was observed among low-risk ALL and B-phenotype ALL. Moreover, the mean serum MTHFR level was 8.01 ng/mL (+/-4.38) in cases and 9.27 ng/mL (+/-4.80) in controls (P < 0.001). MTHFR levels in subjects with 677TT genotype was significantly higher than those with 677CC genotype (P = 0.010) or 677CT genotype (P = 0.043) in controls. In conclusion, our results provide evidence that the MTHFR polymorphisms might contribute to reduced childhood ALL risk in this population.
